US: The Portland Cement Association (PCA) has published a roadmap to carbon neutrality for the cement and concrete sectors by 2050. It says that the strategy document demonstrates how the US cement and concrete industry, along with its entire value chain, can address climate change, decrease greenhouse gases and eliminate barriers that are restricting environmental progress. It added that the document is a ‘major step’ towards engaging US policymakers, industry partners and non-government organisations.

“Cement and concrete have been pivotal in building resilient, durable and sustainable communities that enable people to live safe, productive and healthy lives via structures that withstand natural and man-made disasters,” said PCA President and chief executive officer, Michael Ireland. “The PCA is uniquely positioned to lead the industry-wide ambition to achieving carbon neutrality and enable our member companies and industry partners to continue building a better future.”

The PCA’s roadmap outlines a number of reduction strategies across the various phases of the built environment including production at cement plants, construction including designing and building and everyday infrastructure in use. It also recognises five main areas of opportunity: clinker; cement; concrete; construction; and carbonation (using concrete as a carbon sink).

Notably goals include a reduction of coal and petcoke use at cement plants to 10% in 2050 from 60% at present, a clinker ratio of 75% in 2050 from 90% at present and a reduction of the CO₂ intensity of concrete of 60% by 2050. The roadmap also noted the necessity of carbon capture and storage/utilisation (CCUS) for reducing CO₂ emissions from cement production. However is pointed out that there are no commercial-scale CCUS installations at any cement plant within the US, location and permitting challenges remained and that infrastructure investment would be required to deal with the captured CO2.

World: Forty cement and concrete producers, representing 80% of concrete production outside of China in 2020, have together affirmed their commitment to the Global Cement and Concrete Association (GCCA)’s Roadmap to Net Zero concrete decarbonisation strategy. The roadmap’s seven-point plan consists of increased cement plant efficiency, which should eliminate 22% of emissions, increased concrete production efficiency (11%), adjustments to cement and binders (9%), decarbonisation of raw materials (11%), carbon capture and storage (CCS) (36%), a transition to renewable energy (5%) and the natural recarbonation of concrete (6%).

Besides full decarbonisation by 2050, the strategy provides for a 25% reduction in the global concrete sector’s CO₂ emissions by 2030 and the elimination of 4.9Bnt of CO₂ emissions by 2030 alone. The GCCA called the new commitment a ‘significant acceleration’ of cement and concrete producers’ on-going decarbonisation efforts, and said that it represented ‘the biggest global commitment by any industry’ to carbon neutrality. Acknowledging the burden on cement producers, the GCCA called on downstream companies and governments to support the industry’s transition.

GCCA member China National Building Material (CNBM) CEO Cao Jianglin said “This is a landmark for industry co-operation in decarbonisation. As part of a global industry, it will need collaboration across our sector to achieve it. As one of the leading cement and concrete producers in China, we will play our part in decarbonising the industry.”

South Korea: Sampyo Group has announced a planned investment of US$171m before 2030 to reduce Scope 1 and 2 CO₂ emissions by 35% over the period from an August 2021 baseline. The parent company of Sampyo Cement plans to achieve this in the first phase by increased its use of alternative fuels, improving energy efficiency, introducing low-carbon raw materials such as fly ash and developing sustainable products. The company is targeting net zero CO₂ production by 2050.

Canada: The Cement Association of Canada (CAC) and the government have published a joint statement detailing their plant to develop a roadmap to net-zero carbon concrete. When launched in December 2021, the roadmap will provide Canadian cement producers with the policies, tools and technologies to contribute to the achievement of net-zero concrete by 2050. The plans will cover areas including: supporting the low-emissions building materials supply chain, building an innovative opportunities framework and engaging stakeholders. According to the statement, the roadmap will offer total potential CO₂ reduction of 15Mt by 2030, and 4.0Mt/yr thereafter.

The partnership will establish a CAC-led Industry-Government Working Group in collaboration with the National Research Council the Standards Council of Canada and Innovation, Science and Economic Development. Among its tasks will be the publication of updated environmental product declarations.

Australia: Adbri says it wants to achieve net zero carbon emissions by 2050 as part of its commitment to a low carbon future. The board and management team are assessing medium and long term emissions reduction options and are intend to release a roadmap by the 2022 annual general meeting. Adbri set its current emissions reduction target in 2019, to deliver a 7% reduction in its greenhouse gas emissions by 2024 against 2019 baselines. In 2020 it achieved 2.3% reduction.

“We recognise that process emissions from the production of cement and lime are not easy to abate. Adbri is committed to maintaining its sector leadership position in sustainability by continuing to increase its use of renewable energy, alternative fuels and supplementary cementitious materials. Developments in technology and partnership with industry, government and research institutions will be critical as we deepen our understanding of long term emission reduction options. This will form part of our roadmap toward net zero by 2050,” said Adbri’s chief executive officer Nick Miller.

Switzerland: The Swiss cement association Cemsuisse has published Roadmap 2050, a plan for the achievement of net carbon neutrality by 2050. As part of the plan, the association says that Swiss cement producers will launch carbon capture and storage (CCS) installations at their plants from 2030. Individual companies’ plans also involve the reduction of products’ clinker factors and alteration of cement kiln fuel mixes.

Cemsuisse lobbied the government to approve producers’ mining permits in order to prevent an increase in imports from 686,000t in 2020. The figure corresponds to 15% of the nation’s 4.70Mt consumption.

Spain: The Spanish cement association Oficemen has targeted a 43% emissions drop by 2030 across its entire value chain compared to 1990 levels. The objective has been published as part of the association’s sustainability roadmap to 2050. It is a tightening of the previous target of 27% by 2030. Oficemen intends to meet the tougher reduction by using the so-called 5C approach - clinker, cement, concrete, construction and built environment, and (re)carbonation – as detailed by Cembureau, the European Cement Association. Oficemen also revealed that it is working with the Spanish Technological Platform for CO₂ (PTECO₂) on identifying potential locations for storing captured CO₂. Hugo Morán, Secretary of State for the Environment, participated remotely with the launch event.

Oficemen also reports that Spanish cement consumption fell by 12% year-on-year to 12.2Mt in the first 11 months of 2020. Exports declined by 5%.

Germany: The German Cement Works Association (VDZ) has published a study entitled ‘Decarbonising cement and concrete: a CO₂ roadmap for the German cement industry,’ detailing the planned transformation to cement industry-wide carbon neutrality by 2050.

The study says that a decarbonisation scenario based on conventional reduction measures would cut carbon dioxide (CO₂) emissions by 36% between 2019 and 2050. Chief executive officer (CEO) Martin Schneider said that the sector is already “reaching the limits of its potential for any further reduction in the volume of CO₂, particularly as the process-related emissions specifically associated with clinker production cannot be lowered by employing conventional means." As such, the association proposed a “completely new approach to the production of cement and its use in concrete” in order to realise full climate neutrality. It proposes that cement producers help to reduce concrete’s clinker factor, capturing the remaining CO₂ from necessary cement production.

Schneider said, "We have placed the decarbonisation of cement and concrete at the heart of our activities. It will be essential to achieve an integrated approach, incorporating the entire construction value chain.” In order for this more radical scenario to work, he added, “Another essential factor will be to involve society as a whole in this process."

US: The Portland Cement Association (PCA) says it plans to develop a roadmap by the end of 2021 to help its member companies achieve carbon neutrality across the concrete value chain by 2050. It maintains that ‘concrete is critical to building a sustainable future’ and reinforced the benefits of concrete such as energy efficiency, lower life-cycle costs, durability and resilience. The roadmap is intended to solve problems facing the industry such as developing new technologies to reduce energy consumption and to develop and adopt related regulations.

“As the second most used material on earth and a cornerstone of our economy, we understand the critical role cement and concrete play in our nation’s future, and we are committed to an industry-wide effort that achieves carbon neutrality,” said Tom Beck, chairman of the PCA and president of Continental Cement. Rick Bohan, Vice President, Sustainability for the PCA added, “Developing a roadmap to carbon neutrality by 2050 further demonstrates our industry’s commitment to be a part of the solution and tackle this global issue.”

The PCA says that the industry has reduced energy consumption by 35%, emissions intensity by 11% and since 1990 has increased its use of alternative fuels.

UK: UK Concrete and the Mineral Products Association (MPA) have launched a roadmap for the concrete and cement industry to become net negative by 2050. It plans to do this through decarbonised electricity and transport networks, fuel switching, greater use of low-carbon cements and concretes as well as carbon capture, use or storage (CCUS) technology.

“We have already made significant progress to reduce carbon emissions but are under no illusion about the scale of the net zero challenge,” said Nigel Jackson, chief executive of the MPA. “Achieving this will require the wholesale decarbonisation of all aspects of concrete and cement production, supply and use. The concrete and cement industry as one sector alone cannot deliver net zero and we will only be able to go beyond net zero with concerted support from government, as well as with significant changes across the wider construction, energy and transportation sectors.” He added that the roadmap could be delivered without offsetting emissions, offshoring production facilities or ‘carbon leakage.’

The ‘Roadmap to beyond net zero’ calculates the potential of each technology and the carbon savings which can be achieved. CCUS technology is vital to delivering net zero manufacturing and according to the roadmap will deliver 61% of the required carbon savings. It intends to achieve a net negative industry by 2050 by the ability of concrete to absorb carbon dioxide during use and the thermal properties of concrete in buildings and structures to reduce operational emissions.

The MPA is also lobbying the government for a financial support model including for the capital and operational costs of carbon capture by no later than 2021. This is desired to ensure the technology can be developed, deployed and become an investable proposition in the 2030s.
